TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 280,875,.dated'J'u1y10, 1883.

Application filed May 5, 1883. (No model.)

nexed drawings, making part of this specification, in which- Figure 1 isa side elevation, and Fig. 2 a rear elevation, of a road-cart having theimprovement; Fig. 3, a view in perspective, upon an enlarged-scale, ofthe toggle and the parts immediately therewith connected; and Figs. 4and 5 diagrams showing the movement of the toggle.

The same letters denote the same parts.

The design of this invention is to provide an improved means forpreventing the rocking, jolting motion of the ordinary road-cart.

In consists, in combination, of a fifth-wheel, which support thecart-body at or toward its rear end, anda joint resembling atoggle-joint, which supports the cart-body at or near its forward end.

Aside from its improved features,the roadcart A may be of the customaryform, B representing the cart-body; O, the axle; D D, the wheels; E E,the thills, and F the cross-bar of the thills.

In place of attaching the cart-body or the spring supporting thecart-body directly and rigidly to the cart-axle a fifth-wheel, G, isinterposed between the axle and the body-that is, at or toward its rearend the cart-body is so connected with its support (whether that supportbe the axle or any-spring or part above the axle) as to enable the bodyto swing horizontally thereupon. The preferable mode of pivoting thebody for this purpose is that shown-a fifth-wheel, G, immediately abovethe axle, and connecting the axle with the spring H, which in turnsupports the rear end of the body. .At its forward end the cartbody issupported by means of the jointed 5 connection I. This connection is ofsuch a nature as to enable the cart body to swing laterally upon itsbearing at its rear end, but also so that when the forward end of thebody tends to swing it also tends to lift. This 5c form of connectionresembles, as stated, a toggle-joint having two parts, i and i, jointedtogether at i", to enable one part to turn vertically upon the other.The cart-body, by means of suitable irons, i i, is attached to the 55lower part, i. The upper part, 2', is swiveled at 13* in the cross-bar.The effect of this connection is this: As the shafts .are swayed orvibrated vertically in use, the motions are prevented from beingcommunicated to the cart- 6c body, for the motion of the shafts cannotbe communicated to the cart-body without causing the lower part of thejoint I to turn upon the upper part of the joint I, as indicated inFigs. 4 and 5; but this tends to lift the forward 6 5 end of the body.The weight of the body and the load carried act to resist this tendency,and the practical effect is to largely dissipate the shaft motion andprevent its being felt by the occupants of the cart. 7:

One or more of the joints I can be used at the forward end of thecart-body.

ported by the fifth'wheel and the joint I, substantially as and for thepurpose described. F. J. SPRINGER. O. J. SPRINGER. Witnesses:
